Way back on page 1 I mentioned the Russian Stas's 42 and almost 2 years later I've finally found the info on them after following a couple of leads. I guess everyone is aware of the Marz 2.5 (both diesel and glow) which were made in Russia. When they ceased production in about 1990, Ilya Leydman (who had a business in Sydney called Macheast selling Russian engines) went to Russia in 1992 and, with some Russian friends, bought up most of the Marz machinery with the intention of making his own engine. As a trial run to learn how to make engines they decided on a simple 42 size with design cues based around both Webra and Profi. The Russian manager's son was called Stas so the engine was named Stas's. One of the things they played with was external finish so some had as cast finishes while others had machined fins. In all, they made 200 of the side exhaust and 50 of the rear exhaust. Ilya brought all of them back to Australia where some were then sold to Carlson Imports in America with the remainder being sold through Macheast.
At the top of page 2 Hobbsy mentioned that my Stas's looked similar to his Zeus 61 which just happens to be the engine that Ilya wanted to make

. Ilya told me that he made both the Zeus 42 and 61 as well as a couple of rear exhaust 61's.
For those interested, [link=http://www.holdfastmac.com.au/Stass%27s%2042RE.html]here's[/link] a review I did on my RE version with a photo of my SE which shows the differences in finish.
